7.5 Person declarative metamemory or mnemonic self-concept involves knowledge of person memory-relevant attributes, abilities and limitations including beliefs of oneself and others as mnemonic beings.
7.6 Task declarative metamemory involves knowledge of task variety, characteristics and difficulty facilitating an understanding of task demands. This is also affected by person metamemory.
7.7 Strategy declarative metamemory involves knowledge of various mnemonic strategies and the awareness of their effectiveness in memory task situations. This is affected by person metamemory.
7.8 Interaction among person, task and strategy variables facilitates metamemory and therefore knowledge of the interaction of these memory variables.
7.9 Memory task complexity increases demands upon the interaction between the metamemory variables.
